UCLA Kleinrock Internet History Center

The ARPANET Project Notes collection includes documentation created at or housed by the Network Measurement Center at UCLA, including ARPANET Satellite System (ASS) Notes, notes on packet radio (i.e. Packet Radio Temp Notes), and SPADE admin notes. These all document the development and use of the first Interface Message Processor (IMP)––which functioned similar to a router in today's internet infrastructure––within the world's first large-scale packet-switching network (ARPANET), by UCLA computer scientists and engineers.

In June of 1969, Michael Allen Wingfield, an engineering graduate student, was asked by Steve Crocker at UCLA to design the hardware interface between the Scientific Data Systems (SDS) Sigma 7 computer and an Interface Message Processor (IMP) from Bolt, Beranek and Newman (BBN) to connect the UCLA system as the first node on the Advanced Research Projects Agency Network (ARPANET), the precursor to the internet. After reviewing the BBN 1822 IMP interface specification, Wingfield drew up flow charts, logic diagrams, and a test program for the IMP when it was received from BBN in September 1969. He also implemented …

The UCLA Network Measurement Center was the first node of the Advanced Research Projects Agency Network (ARPANET), located at 3420 Boelter Hall at UCLA. It was run by UCLA Professor Leonard Kleinrock, who has donated his collection of Network Measurement Center documents which include reviews of computer science literature, project notes and reports on the development of the Center's Interface Message Processor (IMP), and various documents related to its role within ARPANET itself.
